ResizableComponent


class ResizableComponent : Component


This Component can be attached to a single instance of an Entity. When attached, this Component will enable the user to resize the Entity by selecting and dragging along the boundaries of a user-resize affordance. While resizing an overlay will appear indicating the proposed updated size.

This component cannot be attached to an AnchorEntity or to the ActivitySpace. Calling Entity.addComponent to an Entity with these types will return false.

Note: This Component is currently unsupported on GltfModelEntity.

Boolean

Whether the content of the Entity, and all child Entities, will be automatically hidden while it is being resized.

Boolean

Whether the aspect ratio is maintained during resizing.

FloatSize3d

FloatSize3d

A lower bound for the User's resize actions, in meters.

Public companion functions

create

Added in 1.0.0-alpha14
fun create(
    session: Session,
    minimumSize: FloatSize3d = kMinimumSize,
    maximumSize: FloatSize3d = kMaximumSize,
    executor: Executor = HandlerExecutor.mainThreadExecutor,
    resizeEventListener: Consumer<ResizeEvent>
): ResizableComponent

Public factory function for creating a ResizableComponent.

This Component can be attached to a single instance of an Entity. When attached, this Component will enable the user to resize the Entity by dragging along the boundaries of a user-resize affordance.

This component cannot be attached to an AnchorEntity or to the ActivitySpace. Calling Entity.addComponent to an Entity with these types will return false.

Parameters
session: Session

The Session to create the ResizableComponent in.

minimumSize: FloatSize3d = kMinimumSize

A lower bound for the User's resize actions, in meters. This value is used to set constraints on how small the user can resize the bounding box of the entity down to. The size of the content inside that bounding box is fully controlled by the application. The default value is 0 meters.

maximumSize: FloatSize3d = kMaximumSize

An upper bound for the User's resize actions, in meters. This value is used to set constraints on how large the user can resize the bounding box of the entity up to. The size of the content inside that bounding box is fully controlled by the application. The default value is 10 meters.

executor: Executor = HandlerExecutor.mainThreadExecutor

The Executor to run the listener on. By default listener is invoked on the main thread.

resizeEventListener: Consumer<ResizeEvent>

A resize event listener for the event. The application should set the size of a PanelEntity using PanelEntity.size.

Public functions

addResizeEventListener

Added in 1.0.0-alpha14
fun addResizeEventListener(
    executor: Executor = HandlerExecutor.mainThreadExecutor,
    resizeEventListener: Consumer<ResizeEvent>
): Unit

Adds the listener to the set of listeners that are invoked through the resize operation, such as start, ongoing and end.

The listener is invoked on the provided Executor if provided.

Parameters
executor: Executor = HandlerExecutor.mainThreadExecutor

The Executor to run the listener on. By default listener is invoked on the main thread.

resizeEventListener: Consumer<ResizeEvent>

The listener to be invoked when a resize event occurs.

onAttach

open fun onAttach(entity: Entity): Boolean

Called by the framework when this component is being added to an Entity.

This method is triggered when Entity.addComponent is invoked. It should not be called directly by applications. Implementations should override this method to perform setup logic or to validate if the component is compatible with the provided entity.

Parameters
entity: Entity

The Entity to which this component is being attached.

Returns
Boolean

true if the component was successfully attached; false if the entity does not support this component or if attachment failed.

onDetach

open fun onDetach(entity: Entity): Unit

Called by the framework when this component is being removed from an Entity.

This method is triggered when Entity.removeComponent is invoked. It should not be called directly by applications. Implementations should override this method to release resources or undo any changes made during onAttach.

Parameters
entity: Entity

The Entity from which this component is being detached.

removeResizeEventListener

Added in 1.0.0-alpha14
fun removeResizeEventListener(resizeEventListener: Consumer<ResizeEvent>): Unit

Removes a listener from the set listening to resize events.

Parameters
resizeEventListener: Consumer<ResizeEvent>

The listener to be removed.

Public properties

affordanceSize

Added in 1.0.0-alpha14
var affordanceSizeFloatSize3d

The current size of the affordance for the Entity, in meters. This property is automatically updated after resize events to match the resize affordance to the newly suggested size of the content. The apps can still override it. The default value is set to 1 meter. If attached to a PanelEntity, this is updated to the size of the Entity when attached.

isAlwaysShowOverlayEnabled

Added in 1.0.0-alpha14
var isAlwaysShowOverlayEnabledBoolean

Whether a resize overlay will be shown even if the entity is not being resized.

This is useful for resizing multiple panels at once.

isAutoHideContentWhileResizingEnabled

Added in 1.0.0-alpha14
var isAutoHideContentWhileResizingEnabledBoolean

Whether the content of the Entity, and all child Entities, will be automatically hidden while it is being resized.

isFixedAspectRatioEnabled

Added in 1.0.0-alpha14
var isFixedAspectRatioEnabledBoolean

Whether the aspect ratio is maintained during resizing.

If true the affordance will maintain its current aspect ratio being resized and all suggested sizes will maintain the current aspect ratio. This defaults to false.

maximumEntitySize

Added in 1.0.0-alpha14
var maximumEntitySizeFloatSize3d

An upper bound for the User's resize actions, in meters. This value constrains large the user can resize the bounding box of the Entity. The size of the content inside that bounding box is fully controlled by the application.

minimumEntitySize

Added in 1.0.0-alpha14
var minimumEntitySizeFloatSize3d

A lower bound for the User's resize actions, in meters. This value constrains how small the user can resize the bounding box of the Entity. The size of the content inside that bounding box is fully controlled by the application.
